Abstract (en)

[origin: WO2012095235A1] The invention relates to a security device and to a method for providing a cryptographic key for a field device (3). Said security device (2) is connected to at least one tamper sensor (8, 9) which is associated with the field device (3) and which, when a physical manipulation carried out on a field device (3) is detected, a manipulation message is emitted. The cryptographic key is only provided to the field device (3) by the security device (2) if said security device (2) does not receive a manipulation message from the tamper sensors (8, 9) associated with the field device.
